hi everyone, after my 3 hour glucose test, my doctor's informed me if my abrnomal results. fasting was normal rnage. 1 hour was high, and 3rd hue was below normal. due to this they referred me to the diabetes center for gestational diabetes. her office also wanted me to take an a1c test to verify. I just took that today with a normal rate of 5.1.

I'm so keeping my consult with the diabetes specialist, but it is next week. has anyone had a similar experience? high number after the 1 hour draw and sudden drop over blood draws 2 and 3? any insight into what it means? do I have gestational diabetes?

I only spoke to my doctors medical assistant, so haven't been able to confirm with my doctor until next week. any insight is appreciated.

Sounds like my results and I have been diagnosed w GD! I passed the fasting draw, failed the 1 hr by 8 points and then was low on the rest! My A1C was 5, which is in normal range and I was still diagnosed :-/!

Yup! My fasting is always low, around 70. After 1 hour my number was sky high, like 250. 2 hour was just over the limit at 160 and 3 hour was way under at 78. I sugar crashed by the time I got home (shaking, sweating, naseous, etc). A1c was 5.2. I was in denial that I had GD at first, but after seeing how my blood sugar reacts to carbs in general (things like beans or potatoes), I don't deny it any more. The diet is hard, but it's only temporary. And once baby is here you can eat whatever again.

The A1C is a measure of average blood glucose levels over a long time period, I think 3 months but don’t quote me on tHat, if you just recently developed gd your A1C would be normal and wouldn’t be elevated unless you had undiagnosed type 2 prior to pregnant or developed gd very early in the pregnancy.

I was diagnosed because of a high fasting number with numbers below the cut off for the blood draws. My a1c was also 5.1. However it was clear to me that I had gd as I couldn’t just carb load and have a good number. I think that if you go super low in one of the draws that also indicates an insulin problem? I’m not exactly sure though as I haven’t had that problem.

This is all so interesting! I had GD with my last pregnancy so they tested me at 5 weeks this time. I failed the 1 hour with 164. My results for the 3 hour were: 85, 182, 134, and 78. I only failed the 1 hour and they said I have to fail 2/4 of the draws to be diagnosed with GD. My a1c was 4.6. I was worried and I talked to my doctor about it. They told me I have “glucose intolerance” and to follow the diet, but not monitor my blood sugar yet. When I asked about just buying my own meter she was kind of rude and dismissed me and told me it wasn’t a good idea because I might obsess over it. Um yes. I will worry about the health of my unborn child. Having had GD before I know that “following a diet” is not enough. We do not always know what things spike us. Clearly she doesn’t have much experience with GD. As I’m reading on here I am noticing that many women were diagnosed when they failed one blood draw on the 3 hour like I did. I’m so worried it will become worse before I’m retested at 24-28 weeks. If something is wrong with my baby because of it I would never forgive myself!

My a1c in my first trimester was 4.5. I went on to fail 2/4 of the 3 hour results, but similarly to you. My fasting was fine, but the one hour was really high. I barely failed the 2 hour and my 3 hour was low. I felt horrible after the test was over. I only failed my 1hr screen with a 132, so I was in denial that I even needed to do the 3 hr and that there was no way I had it. Especially if people can fail the one hour with much higher numbers and pass the 3 hr. Now that I’ve been taking my blood sugars, it’s clear that I have GD. My blood sugar reacts the similarly to how it did in the test. If I have a bad number, it will spike high but go down easily by the 2 hour mark. It’s just the initial spike. I have to be careful about eating my snacks, or I get hypoglycemic. Maybe once you start taking your blood sugar, you will see that you don’t have much issue at all with what you eat and your sugars. I had gd with my first child (not my second, this is my third pregnancy) and I swear I was misdiagnosed. I didn’t have to try very hard and my fastings were 50-60s. Hopefully you’ll be like that. It’s obvious to me I have it this time, because my blood sugars react strange to certain foods and I have sudden highs and lows if I’m not careful.

Actually my OB didn’t test me till 24 weeks but I started the diet since 10 weeks. I asked about getting tested and she said nope just to follow the diet and that I should be fine. Im on my 3rd GD baby so I know what I have to do but it is a little frustrating to be dismissed. So far my sugar levels have been with in range with an occasional spike maybe 3 a week and she said it was fine. Also my test showed i was borderline too. So just do the diet and relax until you have to start checking again. Baby will be fine.
